This market will resolve to the temperature range that contains the highest temperature recorded at the Adolfo Suárez Madrid-Barajas Airport Station in degrees Celsius on 17 Apr '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Adolfo Suárez Madrid-Barajas Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/es/madrid/LEMD. To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C. This market can not resolve to "Yes" until all data for this date has been finalized. The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market. Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.AEMET's latest forecast projects a maximum temperature of 27°C at Adolfo Suárez Madrid-Barajas Airport on April 17 under a stable high-pressure ridge promoting clear skies and light winds, driving trader consensus with 27°C leading at 40% implied probability, closely trailed by 26°C (28.5%) and 28°C (23.5%). This reflects a warming trend from April 15's observed 21.2°C high and April 16's near-20°C readings, bolstered by ECMWF and GFS ensemble means converging on the 26–28°C range amid above-normal seasonal outlooks for Spain. Historical April averages hover around 18–20°C, but current anticyclonic conditions favor intensification; traders await final AEMET updates and model refreshes today, as small shifts in solar heating or cloud cover could adjust outcomes within this tight cluster.
